Hi - again the iphone has a custom back plate - not sure why the original owner decided to do this, looks awful IMO, it is like a transparent back plate - you can see the iphone's internals, battery etc.. I am quite sure this means the warranty is void, even eliminating the option for me to pay to have it replaced (which I probably would tbh). It is actually within the original 12 month period - until Feb 2013 actually.
